SILICATE COMPOSITION.

Io Drawing.

T 0 all whom it may concern Be it known that I, Lion SEIDEMAN, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Silicate Composition, of which the following is a full. clear, and exact description.

This invention relates to silicate compositions, and has reference more particularly to a composition containing silicate and an oily substance, said composition being adapted to serve as a bronzing or other metallic paint liquid or vehicle, as a leather dressing or as a substitute for varnish and shellac.

An ob'ect of this invention, therefore. is to provlde a silicate composition of the class indicated which is incombustible. inodorous, dries quickly with a brilliant gloss, and mixes well with bronze powder, inks, dyes, or other substances.

Another object of this invention is to provide a composition which may be used as a substitute for varnish and shellac.

A further object of this invention is to provide brpnzing liquid which will maintain thecolor ofthe bronze without causing same tidinken.

My composition consists essentially of a mixture of sodium silicate or other silicates with a substance such as glycerine, corn oil, etc. Sodium silicate is usually sold commercially at a density of 40 Be. and I find that a density of 20 B. is most desirable for use as a bronzing liquid. To one fluid ounce of water. I add three ams 0 an 01 y su s ance such as l I l l l I 1, ounce of 40 B. sodium silicate. suiting composition will readily mix with bronze powder and will quickly dry after appllcatlon to the substance to be bronzed. The glycerine greatly assists in causing the sodium silicate to mix with the bronze powder and also increases the spreading power of the bronzing liquid. The glycerine or other oily substance also servesfto conceal the particles of sodium carbonate formed by the action of the carbon dioxide in the air on the sodium silicate since these particles would otherwise give a white, obectionabl e, dusty appearance to the bronzed Application filed June 2,

articles after the bronzing liquid has dried. My bronzing metallic paint containing the bronze owdgr, the sodium silicate, and the g ycerine, oes not da'rkeh in color as it dr'isbn the article, as frequently occurs with other bronzing compositions, but my composition will dry to a slightly lighter color which is more desirable. My silicate composition can also be used for the application of other metallic powders such as silver. gold, aluminum, etc.

This bronzing liquid has many advantages in that it is incombustible and renders the article to which it is applied incombustible, is inodorous. flows freely, and is very quick-drying. With my improved liquid, it is possible to apply bronze. old. ilv aluminum orp t h u- J owers to g ass, porce am or other ceramic prouc s without firing which would be otherwise necessary, since the sodium silicate combines chemically with the glass. The lvcerine ma y sacrificing som eTf tlT.- good qualities of my bronzing composition, and when the composition is used as a leather dressing, the glycerine is preferably omitted. I have found that the 20 B. WW! solultiolq mixes1 readlly with 1n I yes, etc., an t e resu ting mixture produces a leather dressing which gives a very smooth and serviceable gloss, and after said dressing is worn off. the leather remains soft and smooth. This leather dressing also dries quickly, is inodorous. and renders the leather incombustible.

I have also found that the sodium silicate mixed with an oily substance such as.

corn oiLis a very desirable su 'va'r n'isfi and shellac since it spreads easily, gives a very ar sur ace w1 a 1;; g oss equal to that of glass, and renders the articles which are coated with my composition i combustible.

For use as a varnish prefer mlxinglmfi siderably varied without'departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I 5 claim as new and desire to secure by Letters Patent:

1. A composition of matter, which comprises one fluid ounce of sodium silicate having a density of 40 B., and one drop of corn oil.

2. A metallic paint composition which consists of a water-soluble silicate, a vegetable oil, and a metallic powder.
